Habitat and ecologyH. jacksoni is nearly always found in wet or marshy areas, in bogs and heathland. Adults of both sexes have been found in autumn, winter and spring, females also in the summer.

StatusThe species is uncommon but it can be frequent in damp heathy areas and bogs in southern England. An apparent decline needs more information to evaluate.
